Does your home have an underground heating oil tank? How can you find out?
The only way to know for sure if a tank is still buried is to have an oil tank search performed. That said, there are a few things you can on your own to see if a tank is even likely. This involves looking for evidence of a previous or existing tank, and looking for records related to oil tanks.
The first thing you want to think about is the age of the home. Homes build after 1980 will almost never have an oil tank. But any home might have a tank if it were built in the 70ss or before. This is also true if the neighborhood itself was already there prior to the 1970’s.
